Localization Of Open Educational Resources (Oer) In Nepal: Strategies Of Himalayan Knowledge-Workers, Tiffany Ivins Mar 2011

Localization Of Open Educational Resources (Oer) In Nepal: Strategies Of Himalayan Knowledge-Workers, Tiffany Ivins

Theses and Dissertations

This dissertation examines localization of Open Educational Resources (OER) in Himalayan community technology centers of Nepal. Specifically, I examine strategies and practices that local knowledge-workers utilize in order to localize educational content for the disparate needs, interests, and ability-levels of learners in rural villages. This study draws on insights from non-formal education (NFE) stakeholders in Nepal, including government, UN, international and national NGOs, local knowledge-workers, and learners from different villages. I specifically focus on a sample of seven technology centers to better understand how localization is defined, designed, and executed at a ground level. I illuminate obstacles knowledge-workers face while …

De Novo Genome Assembly And Snp Marker Development Of Pyrenophora Semeniperda, Marcus Makina Soliai Mar 2011

De Novo Genome Assembly And Snp Marker Development Of Pyrenophora Semeniperda, Marcus Makina Soliai

Theses and Dissertations

Pyrenophora semeniperda (anamorph Drechslera campulata) is a necrotrophic fungal seed pathogen of a variety of grass genra and species, including Bromus tectorum, an exotic grass that has invaded many natural ecosystems of the U.S. Intermountain West. As a natural seed pathogen of B. tectorum, P. semeniperda has potential as a biocontrol agent due to its effectiveness at killing dormant B. tectorum seeds; however, few genetic resources exist for this fungus. Here, the genome assembly of a P. semeniperda isolate using 454 GS-FLX genomic and paired-end pyrosequencing techniques is presented. The total assembly is 32.5 Mb and contains …

A Gis-Based Data Model And Tools For Analysis And Visualization Of Levee Breaching Using The Gssha Model, Hoang Luu Tran Mar 2011

A Gis-Based Data Model And Tools For Analysis And Visualization Of Levee Breaching Using The Gssha Model, Hoang Luu Tran

Theses and Dissertations

Levee breaching is the most frequent and dangerous form of levee failure. A levee breach occurs when floodwater breaks through part of the levee creating an opening for water to flood the protected area. According to National Committee on Levee Safety (NCLS), a reasonable upper limit for damage resulting from levee breaching is around $10 billion per year during 1998 and 2007. This number excludes hurricanes Katrina and Rita in 2005 which resulted in economic damages estimated to be more than $200 billion dollar and a loss of more than 1800 lives. In response to these catastrophic failures, the U.S. …

Usage And Development Of Molecular Markers For Investigation Of The Population And Ecological Genetics Of Bromus Tectorum L., Keith R. Merrill Mar 2011

Usage And Development Of Molecular Markers For Investigation Of The Population And Ecological Genetics Of Bromus Tectorum L., Keith R. Merrill

Theses and Dissertations

This thesis includes two studies: The first examined patterns of neutral genetic diversity within Bromus tectorum L. across the IMW region, and uses patterns of microsatellite (SSR) genotype distribution to make inferences about the respective roles of adaptively significant genetic variation, adaptive phenotypic plasticity, and facultative outcrossing in the ongoing invasion and recent range expansion of B. tectorum. It has been previously demonstrated that, due to extremely low outcrossing rates, it is possible to characterize individual genotypes of this species using four SSR loci. We sampled 20 individuals from each of 96 B. tectorum populations (classified by region and …

Apparent Competition With Bromus Tectorum Through Pyrenophora Semeniperda Reduces Establishment Of Native Grasses, Katherine Temus Merrill Mar 2011

Apparent Competition With Bromus Tectorum Through Pyrenophora Semeniperda Reduces Establishment Of Native Grasses, Katherine Temus Merrill

Theses and Dissertations

Contributing to the success of Bromus tectorum in the Intermountain West may be a mechanism called apparent competition, which occurs when one species increases the pressure of a consumer on a second species. This indirect interaction has been documented only a few times in invasive plant systems, and never in a fungal pathosystem. We examined the effects of the invasive annual Bromus tectorum and predation by the seed pathogen Pyrenophora semeniperda on seedling emergence and survival for two native grasses (Pseudoroegneria spicata and Elymus elymoides), by manipulating B. tectorum densities and P. semeniperda inoculum loads in randomized plots. …

A Proteolytic Process To Simulate The Mechanics Of Disc Dengeration In Bovine Cadaveric Tissue, Timothy A. Bishop Mar 2011

A Proteolytic Process To Simulate The Mechanics Of Disc Dengeration In Bovine Cadaveric Tissue, Timothy A. Bishop

Theses and Dissertations

Purpose. The present work hypothesized that proteolytic dissolution of intervertebral discs could induce biomechanical change comparable to the change observed in natural disc degeneration. A method to do such could be utilized for in vitro research where intersample differences in geometry and chemical makeup render it difficult to compare and aggregate results into generalized conclusions.
Methods. Forty-one bovine coccygeal intervertebral discs were isolated with individual functional spinal units. Samples were loaded in three modes: compression/tension, flexion/extension, and axial rotation. The anulus fibrosus of each disc was injected with 200µl trypsin or fetal bovine serum (control) and incubated for an allotted …

Developing Methods To Assess The Potential Effects Of Global Climate Change On Deer Creek Reservoir Using Water Quality Modeling, Reed Earl Chilton Mar 2011

Developing Methods To Assess The Potential Effects Of Global Climate Change On Deer Creek Reservoir Using Water Quality Modeling, Reed Earl Chilton

Theses and Dissertations

To evaluate the potential impacts of future climate change on a temperate reservoir, I used a calibrated water quality and hydrodynamic model validated using three years of data (2007-2009) from Deer Creek Reservoir (Utah). I evaluated the changes due to altered air temperatures, inflow rates, and nutrient loads that might occur under Global Climate Change (GCC). I developed methods to study GCC on reservoirs. I produced Average Water Temperature Plots, Stratification Plots, and Total Concentration Plots. Average Water Temperature Plots show the sensitivity of the water temperature to various parameters. Stratification Plots quantify stratification length and strength as well as …

Culvert Roughness Elements For Native Utah Fish Passage: Phase I, Lindsay D. Esplin Mar 2011

Culvert Roughness Elements For Native Utah Fish Passage: Phase I, Lindsay D. Esplin

Theses and Dissertations

Culverts can increase stream velocities as a result of reduced waterway areas and prevent upstream passage of small non-salmonid fish such as the Native Utah Leatherside chub (Gila copei) and Longnose dace (Rhinichthyscataractae). To mitigate this problem, current culvert design standards for fish passage match sustained fish swim speeds with average cross sectional velocity through the culvert. Such policies dictate relatively large barrels and do not recognize the role of reduced velocity zones near culvert boundaries. Obstacles and streambed substrate create turbulent regions with lower velocity zones that can increase upstream fish passage. A comparison of …

Easy To Find: Creating Query-Based Multi-Document Summaries To Enhance Web Search, Rani Majed Qumsiyeh Mar 2011

Easy To Find: Creating Query-Based Multi-Document Summaries To Enhance Web Search, Rani Majed Qumsiyeh

Theses and Dissertations

Current web search engines, such as Google, Yahoo!, and Bing, rank the set of documents S retrieved in response to a user query Q and display each document with a title and a snippet, which serves as an abstract of the corresponding document in S. Snippets, however, are not as useful as they are designed for, i.e., to assist search engine users to quickly identify results of interest, if they exist, without browsing through the documents in S, since they (i) often include very similar information and (ii) do not capture the main content of the corresponding documents. …

The Portrayal Of Older Characters In Popular Children's Books: A Content Analysis From 2000 To 2010., Jesica L. Danowski Mar 2011

The Portrayal Of Older Characters In Popular Children's Books: A Content Analysis From 2000 To 2010., Jesica L. Danowski

Theses and Dissertations

While picture books are often viewed as educational resources for young readers, it is crucial to not overlook the images and content this literary medium contains. Research suggests that repetitive messages encompassing a stereotypical nature cultivate lasting impressions on young audiences. One portrayal often associated with negative implications is the depictions of older characters in children's first literature. This investigation analyzed a selection of picture books from the New York Times best sellers list, the Book Sense best sellers list, and the Caldecott award winners for the years 2000–2010. In an attempt to provide a time spectrum communicating the levels …

Human Endogenous Sodium Pump Inhibitors Measurement, Source, Synthesis And Regulation, Jie Ma Mar 2011

Human Endogenous Sodium Pump Inhibitors Measurement, Source, Synthesis And Regulation, Jie Ma

Theses and Dissertations

The sodium pump (SP or Na+,K+-ATPase) is a membrane embedded protein complex that pumps 3 sodium ions out and 2 potassium ions into the cell per cycle and in so doing creates a cell membrane electrochemical potential. The membrane potential is critical for any functional cell. In the vasculature, reduction in the voltage potential causes vascular smooth muscle contraction and a narrowing of blood vessels (vasoconstriction) which can lead to increased blood pressure (hypertension). Substantial research over the past several decades has provided a vast amount of research on SP inhibitors, sometimes called endogenous digitalis-like factors (EDLF). Increased levels of …

The Effects Of Acute And Chronic Nicotine On Gaba And Dopamine Neurons In The Midbrain Ventral Tegmental Area, Devin Hardy Taylor Mar 2011

The Effects Of Acute And Chronic Nicotine On Gaba And Dopamine Neurons In The Midbrain Ventral Tegmental Area, Devin Hardy Taylor

Theses and Dissertations

Nicotine (NIC) abuse involves activation of midbrain dopamine (DA) neurons and NIC addiction involves neuroadaptive changes in the mesolimbic DA reward system. GABA neurons in the midbrain ventral tegmental area (VTA) express α4β2-containing nicotinic acetylcholine receptors (nAChRs), whose activation increases GABAergic input to DA neurons. However, this initial effect is decreased after chronic NIC treatment (as in the case of smokers) by inducing nAChR desensitization. Thus, GABA neuron inhibition results in increased DA release in limbic structures such as the nucleus accumbens. To support this hypothesis, we evaluated the effects of acute and chronic NIC on GAD-67 positive neurons in …

A Novel Use Of Digoxin Immune Fab Fragment In Identification And Isolation Of An Endogenous Digitalis-Like Factor Found In Preeclampsia, Moana Lee Hopoate-Sitake Mar 2011

A Novel Use Of Digoxin Immune Fab Fragment In Identification And Isolation Of An Endogenous Digitalis-Like Factor Found In Preeclampsia, Moana Lee Hopoate-Sitake

Theses and Dissertations

The mechanisms mediating the hypertension of preeclampsia (PE) are unclear. Endogenous digitalis-like factors (EDLFs) are specific sodium pump (SP) inhibitors implicated in essential and experimental hypertension, but they have not been fully explored in the setting of PE. This study uses a digoxin antibody Fab fragment to address the question of whether such factors are present and increased in PE, to investigate a possible treatment of PE, and to isolate and characterize all EDLFs present in PE. Sera and placenta from women with PE did show a significant increase in SP inhibition in comparison to women with normal pregnancy and …

The Functions Of Guilt And Shame In Juan José Millás' El Mundo And My Olive-Green Fridge And I: The Posthuman Identity In El Púgil, Constantin Cristian Icleanu Mar 2011

The Functions Of Guilt And Shame In Juan José Millás' El Mundo And My Olive-Green Fridge And I: The Posthuman Identity In El Púgil, Constantin Cristian Icleanu

Theses and Dissertations

In his celebrated 2007 novel El mundo, Juan José Millás tells the story of the development of Juanjo, a simulacrum of himself, and describes a series of negative developments that the protagonist faces in his childhood. While much has been written about Millás and the “testimonial realism” of his literary generation, little has been written about the psychological factors that influence his characters. In this paper I analyze Juanjo's development as understood from the gradation of guilt to shame, depression, and later suicidal thoughts. Because Juanjo is not able to find an appropriate mechanism of release for his guilt, …

Portrayals Of Relational Aggression In Popular Teen Movies: 1980-2009, Halie Ann Foell Stout Mar 2011

Portrayals Of Relational Aggression In Popular Teen Movies: 1980-2009, Halie Ann Foell Stout

Theses and Dissertations

The media is littered with various portrayals of aggression. This aggression has been shown to influence the attitudes, beliefs, and subsequent behaviors of its viewers (Bushman & Anderson, 2001). Relational aggression is a newer concern for researchers and has become more prevalent in recent research. Relational aggression is prevalent in the lives of adolescents. Using social cognitive theory (Bandura 2002), information processing theory (Huesmann, 1988), and the general aggression model (Anderson & Bushman, 2002) to justify how adolescents might be developing these relationally aggressive behaviors, this study seeks to expand the literature by evaluating the portrayals of relational aggression in …

Evolution And Emergence Of The Hinterland In The Active Banda Arc-Continent Collision: Insights From The Metamorphic Rocks And Coral Terraces Of Kisar, Indonesia, Jonathan R. Major Mar 2011

Evolution And Emergence Of The Hinterland In The Active Banda Arc-Continent Collision: Insights From The Metamorphic Rocks And Coral Terraces Of Kisar, Indonesia, Jonathan R. Major

Theses and Dissertations

Coral terrace surveys and U-series ages of coral and mollusk shells yield a surface uplift rate of ~0.6 m/ka for Kisar Island. The small island is located NE of Timor in the active Banda Arc of Indonesia. Based on this rate, Kisar first emerged from the ocean as recently as ~450 ka. Terrace surveys show warping that follows a pattern of east-west striking folds, which are along strike of thrust-related folds of similar wavelength imaged by a seismic reflection profile just offshore. This deformation shows that the emergence of Kisar can be attributed to forearc closure along the south-dipping Kisar …

Emulating Gossip Girl: Aggressive And Prosocial Material In Adolescent Novels And Associations With Behavior, Laura Ann Stockdale Mar 2011

Emulating Gossip Girl: Aggressive And Prosocial Material In Adolescent Novels And Associations With Behavior, Laura Ann Stockdale

Theses and Dissertations

Decades of researchers have found that exposure to aggressive content in multiple forms of media is associated with both physically (Bushman & Anderson, 2001) and relationally (Coyne, Nelson, Graham-Kevan, Keister, & Grant, 2010) aggressive behavior. Similarly, other researchers have found that exposure to prosocial content in multiple forms of media is associated with increased prosocial behavior (Mares & Underwood, 2008). While these associations have been studied in a variety of media, books as a form of media have received less research attention. The current study examined the associations between the content of adolescents' favorite novels and their normative beliefs about …

Letting Go And The Silence That Remains: The Effects Of Translating Point-Of-View From Text To Film In The Remains Of The Day And Never Let Me Go, Jennifer L. Price Mar 2011

Letting Go And The Silence That Remains: The Effects Of Translating Point-Of-View From Text To Film In The Remains Of The Day And Never Let Me Go, Jennifer L. Price

Theses and Dissertations

Kazuo Ishiguro's novels The Remains of the Day and Never Let Me Go exhibit many of the same characteristics as his other works. Out of all of those works, however, only these two novels have been adapted to film as of yet. Because of Ishiguro's reliance on first-person narration and point-of-view his novels are particularly more problematic to adapt to screen. This phenomenon is partially due to the audio-visually dependent medium of film and the camera lens' limitations when it comes to exhibiting character interiority. Therefore, the effect of the translation to screen for both of these films is a …

The Mountain Meadows Massacre Of 1857: A Civilizational Encounter With Lessons For Us All, Michael Andregg Mar 2011

The Mountain Meadows Massacre Of 1857: A Civilizational Encounter With Lessons For Us All, Michael Andregg

Comparative Civilizations Review

Between September 7 and 11 of 1857, an emigrant (pioneer) wagon train was attacked while traveling through southern Utah toward California. At the end of the attack, 120 were killed, sparing only 17 or perhaps 18 children considered too young to talk about it. In the annals of war and slaughter, this could be considered a tiny event. But for the history of the Great Basin of North America, it was quite exceptional. More white pioneers died on the Mountain Meadows than during any other violent event in the history of the American west. For civilizationalists, this is important as …

Thermodynamic, Sulfide, Redox Potential, And Ph Effects On Syngas Fermentation, Peng Hu Feb 2011

Thermodynamic, Sulfide, Redox Potential, And Ph Effects On Syngas Fermentation, Peng Hu

Theses and Dissertations

Recently, work in ethanol production is exploring the fermentation of syngas (primarily CO, CO2, and H2) following gasification of cellulosic biomass. The syngas fermentation by clostridium microbes utilizes the Wood-Ljungdahl metabolic pathway. Along this pathway, the intermediate Acetyl-CoA typically diverges to produce ethanol, acetic acid, and/or cell mass. To develop strategies for process optimization, a thermodynamic analysis was conducted that provided a detailed understanding of the favorability of the reactions along the metabolic pathway. Thermodynamic analysis provided identification of potentially limiting steps. Once these limiting reactions were identified, further thermodynamic analysis provided additional insights into the ways in which reaction …

Species Trees And Species Delimitation With Multilocus Data And Coalescent-Based Methods: Resolving The Speciation History Of The Liolaemus Darwinii Group (Squamata, Tropiduridae), Arley Camargo Bentaberry Feb 2011

Species Trees And Species Delimitation With Multilocus Data And Coalescent-Based Methods: Resolving The Speciation History Of The Liolaemus Darwinii Group (Squamata, Tropiduridae), Arley Camargo Bentaberry

Theses and Dissertations

The inference of species boundaries and phylogenetic relationships are fundamental for evolutionary, ecological, and conservation studies. The resolution of species boundaries and the inference of phylogenetic relationships among species are required to define the units of analysis and to find the most closely related units for evaluating alternative models of speciation. I highlight lizards as model organisms for ecological and evolutionary studies, emphasizing their contributions to advances in understanding linkages between phylogeography and speciation. In this dissertation, I focus on the phylogenetic relationships of the lizards in the Liolaemus darwinii group, and the species boundaries of a nested clade within …

Bats Of Mesa Verde National Park, Colorado: Composition, Reproduction, And Roosting Habits, Thomas J. O'Shea, Paul M. Cryan, E. Apple Snider, Ernest W. Valdez, Laura E. Ellison, Daniel J. Neubaum Jan 2011

Bats Of Mesa Verde National Park, Colorado: Composition, Reproduction, And Roosting Habits, Thomas J. O'Shea, Paul M. Cryan, E. Apple Snider, Ernest W. Valdez, Laura E. Ellison, Daniel J. Neubaum

Monographs of the Western North American Naturalist

We determined the bat fauna at Mesa Verde National Park (Mesa Verde) in 2006 and 2007, characterized bat elevational distribution and reproduction, and investigated roosting habits of selected species. We captured 1996 bats of 15 species in mist nets set over water during 120 nights of sampling and recorded echolocation calls of an additional species. The bat fauna at Mesa Verde included every species of bat known west of the Great Plains in Colorado, except the little brown bat (Myotis lucifugus). Some species showed skewed sex ratios, primarily due to a preponderance of males. Thirteen species of bats …
